Say the 1% 10y $100 bond is now worth $80 and there are now 5% bonds available. Say the monkey NFT is down from $100 to $80. The monkey NFT could be sold and 5% bonds could be bought, which will also pay out >$100 eventually.
The second bank has just bought - because it has enough money to do so selling its NFT or whatever - the same bonds that SVB has.
There is no difference at all between the assets of liabilities and the two banks in this example. I don’t mean just that the amounts are the same: every asset is identical.
Can both use the “I have the money but just not right now” excuse or not?
Unlike NFTs or whatever, the bonds held to maturity will pay out the full amount.
